I-API factory PDC Bi Center Bit for Under Reamer drilling

I-BI center bit isetshenziselwa ukwenza kabusha imbobo phansi, imodeli No. ithanda 5 7/8″*7 1/2″*4 3/4″ noma nje 5 7/8″*7 1/2″ njengoba ububanzi besithathu bunjalo. akubalulekile.

I-5 7/8″ iyi-diameter edlulayo, i-7 1/2" ububanzi bokubuyisela kabusha, 4 3/4" ububanzi bebhithi yangaphambili.

I-Far Eastern imboni igxile kakhulu ekubholeni, okufana ne-roller cone bit, i-tricone roller cone bit, i-tricone bits, i-HDD hole opener, i-Foundation roller cutters yezinhlelo zokusebenza ezahlukene. Uhlelo lokusebenza oluhlanganisa indawo kawoyela, igesi yemvelo, ukuhlola kwendawo, ukubhoreka kwe-driectional, izimayini, ukumba umthombo wamanzi, i-HDD, ukwakhiwa, kanye nesisekelo.
Njengefekthri ehamba phambili yama-drill bits e-China, sihlose ukukhulisa impilo yokusebenza ye-drill bit. Sihlala sizama ukuthuthukisa izingcezu ngezinga eliphezulu lokungena.Inhloso yethu ukuthengisa ikhwalithi ephezulu ngentengo ephansi kakhulu.Ikhwalithi yokumba empumalanga ekude kanye nobuchwepheshe buzokusiza ukuzuza okwengeziwe.
